PROTOTYPE
A teardrop becomes moody blue when lit from the inside.
The prototype was constructed of white felt with a blue stitch.
Eyes were glued to the inside with the idea of revealing the mood when turned on.
4 LED’s were connected in parallel to the battery (resistors will be needed for the final design), then inserted into styrofoam spheres for diffusion.

DIFFUSION TESTS
I tested several methods for diffusing the LED light.
Nylon Mesh Weave
Glow in the dark “fingers”
Ping Pong Balls
Polypropylene tubes
Styrofoam spheres
and Opaque plastic cylinders
In the end, I found the Styrofoam spheres to deliver the best look to the diffusion. The ping-pong balls were a close second, but too large for the concept I’m thinking about.
